From 626ede6b1aafb3a8cadfdd04b512fd1d3dc2113e Mon Sep 17 00:00:00 2001 From: Pavel Roskin Date: Thu, 18 Feb 2010 20:28:02 -0500 Subject: ath5k: remove stale function declarations, make some functions static Remove all unnecessary function declarations from ath5k.h. Comment out unused functions. Remove ath5k_hw_get_tsf32(), which is too trivial to be commented out. Make functions static if suggested by sparse. Make ath5k_pm_ops static.

This is not very clear in the code right now, unfortunately. Introduce a new IWL_TX_FIFO_UNUSED constant and make the queue/FIFO mapping arrays able to hold that value, and change the setup code to reserve all queues in the arrays (the queue number is the index) and use the new unused constant to not map those queues to any FIFO. Additionally, clear up the AC/queue mapping code to be more understandable. The mapping is the identity mapping right now, but with the mapping function I think it's easier to understand what happens there. Finally, HCCA isn't implemented at all and I think newer microcode removed it, so let's remove all mention of it in the code, some comments remain for 4965.

This is not correct since the HW does padding on RX (and expect the same padding to be present on TX) at the following position : - management : 24 + 6 if 4-addr format - control : 24 + 6 if 4-addr format - data : 24 + 6 if 4-addr format + 2 if QoS - invalid : 24 + 6 if 4-addr format whereas ieee80211_get_hdrlen_from_skb() is : - management : 24 - control : 16 except for ACK/CTS where it is 10 - data : 24 + 6 if 4-addr format + 2 if QoS + 2 if QoS & order - invalid : 24 So, correct frames are not affected : management frames do not use 4-addr format, control frames have no body and invalid frames are ... not valid by definition. However, in order to use monitor interface for debugging purpose, one must be able to send/receive any frames, be it correct or not. Such frames are affected by incorrect padding. Moreover, since padding is added on TX, we need to remove it before calling ieee80211_tx_status. This affect TX packets received by monitor interfaces. It has been tested between an ath5k based card (AR5212) and an ar9170usb based card (netgear WNDA3100) using a frame generator and a monitor interface for each card. v2: Added ath5k_add_padding / ath5k_remove_padding Signed-off-by: Benoit Papillault Signed-off-by: John W.

It was renamed to "libipw", but some occurrences of the old name remained. Rename alloc_ieee80211() to alloc_libipw() and free_ieee80211() to free_libipw(). Adjust comments and label names.

The main change is a 21 bit address split into a 5 bit device ID and a 16 bit register offset. The definition is designed so that normal and extended devices can run on the same MDIO bus. Extend mdio-bitbang to do the new protocol. At the MDIO bus level the protocol is requested by or'ing MII_ADDR_C45 into the register offset. Make phy_read/phy_write/etc pass a full 32 bit register offset. This does not attempt to make the phy layer support C45 style PHYs, just to provide the MDIO bus support. Tested against a Broadcom 10GE phy with ID 0x206034, and several Broadcom 10/100/1000 Phys in normal mode. Signed-off-by: Jason Gunthorpe Signed-off-by: David S.

Change this to only add the broadcast station when interface is added by mac80211. With this we need some extra work to ensure broadcast station is always present since station table is cleared when RXON without ASSOC bit set is sent. To deal with this we re-add all driver known stations to uCode after such an RXON command is sent. We also do some cleanup and remove the various calls to clear the station table. We now only clear the station table in two scenarios: - only clear uCode portion of station table when RXON command without ASSOC bit is sent - clear uCode and driver portion when interface goes down or is removed. We need to do this clearing when interface goes down to deal with the device restart/reconfigure routines which do not remove the interface, but do add the interface during reconfiguration. Previously the keys were also cleared when station table in driver is cleared, this is not done anymore since mac80211 will take care that keys are set and cleared correctly. There is a known issue with this change. Associating with different AP without bringing interface down fails with a firmware error. This is because of the lack of full station notification support and the later patches in this series that complete the station notification support will fix this.

The benefot from these new callbacks are that they enable the driver to sleep while performing this work. This is a big patch since a few things need to be coordinated in this move. First we need to decouple station management from rate scaling, which caused a lot of code to be moved and/or deleted. Next we needed to tie in with mac80211's station management callback and let it direct our station management as well as trigger the rate scaling initialization.

When a queue is stuck for some unknown conditions causing the throughput to drop and the transfer is stop, the driver will force firmware reload and bring the system back to normal operational state. The iwlwifi devices behave differently in this regard so this feature is made part of the ops infrastructure so we can have more control on how to monitor and recover from tx queue stall case per device.

The history buffer supports collecting information for all Atheros hardware, one history buffer slot for each chain on each channel used for MIMO operation. For current hardware this means one history buffer slot for each chain on both the control (or primary) channel and the extension (or secondary) channel. We know which noisefloor registers to poke for collecting noisefloor data through the chainmask. For AR9285 and AR9271 devices, both 1x1, the chaimmask is defined as 0x9 = 0b0001001. The first four bits represent each chain out of a maximum of 4 chains [0-3] on the primary channel. The last four bits represent each chain on the extension channel. A chainmask of 0x9 therefore indicates chain 1 is active on both the primary and the extension channel. AR9271 only requires collecting and storing noisefloor history buffer data for the first chain on both the control and extension channel (nfarray[0] and nfarray[3]) so fix the code and avoid which reads and writes to the history buffer for the other chains. Since the noisefloor varies depending on the number of chains your device supports also initialize the noisefloor history buffer with reasonable values seen on 1x1 devices such as AR9285.

Date: Fri, 26 Mar 2010 11:36:47 +0000 Subject: igb: add per-packet timestamping This patch adds support for per-packet timestamping for the 82580 adapter. The rx timestamp code is also pulled out of the inlined rx hotpath and instead moved to a seperate function.

Previous behaviour is of course still supported. Convert the two in-tree users to this feature (icontrol & zeus). Tested on an Zeus platform (mcp2515).

Mac stack do the same, so we do not need repeat that work here. Stack also will tell when disable QoS, this will fix driver when working with older APs, that do not have QoS implemented. Patch make "force = true" in iwl_active_qos() assuming we always want to do with QoS what mac stack wish. Patch also remove unused qos_cap bits, do not initialize qos_active = 0, as we have it initialized to zero by kzalloc. Signed-off-by: Stanislaw Gruszka Signed-off-by: John W.

This is useful for making it possible to allocate the intermediate rx status data separately. Signed-off-by: Felix Fietkau Signed-off-by: John W.

The existing CONFIG_PPPOL2TP config option is left in its current place to avoid "make oldconfig" issues when an existing pppol2tp user takes this change. (This is the same approach used for the pppoatm driver, which moved to net/atm.) There are no code changes. The existing drivers/net/pppol2tp.c is simply moved to net/l2tp.

In L2TPv3, protocols other than PPP can be carried, so this split creates a common L2TP core that will handle the common L2TP bits which protocol support modules such as PPP will use. Note that the existing pppol2tp module is split into l2tp_core and l2tp_ppp by this change. There are no feature changes here. Internally, however, there are significant changes, mostly to handle the separation of PPP-specific data from the L2TP session and to provide hooks in the core for modules like PPP to access.

The chip architecture has also changed enough that any debugging effort that might use it would have to tailor it to the capabilities of the hardware. This patch just removes the function entirely.

Those masks differ in many bits. Use ah->imask instead of ah->mask_reg in ath9k_hw_set_interrupts() and ath9k_hw_updatetxtriglevel(). That's what the code was meant to do. ah->imask is initialized in ath9k_start(), so we don't need to initialize it from ah->mask_reg. Once it's done, ah->mask_reg becomes write-only, so it's replaced with a local variable in ath9k_hw_init_interrupt_masks().

The patch also updates the driver so that it runs on the MicroBlaze. The changes were tested on the PowerPC 440, PowerPC 405, and the MicroBlaze platforms.

The modification is in usbnet.c function usbnet_start_xmit(). This patch only adds the zero length flag. A subsequent patch will address the buggy code we found when devices do not advertise FLAG_SEND_ZLP in which case there is a possibility of transferring packets with non-deterministic length. This patch has been tested on kernel-2.6.34-rc3. This patch has been checked against net-2.6 tree. Signed-off-by: Elina Pasheva Signed-off-by: Rory Filer Signed-off-by: David S.

I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf Signed-off-by: John W.

There are obvious race conditions here, besides which: 1. The test for availability is done by passing a NULL handler, which now always returns -EINVAL, thus the device cannot be opened: 2. probe_irq_off() will report only the first ISA IRQ handled, potentially leading to a false negative. There was another bug that meant it ignored all error codes from request_irq() except -EBUSY, so it would 'succeed' despite this (possibly causing conflicts with other ISA devices). This was fixed by ab08999d6029bb2c79c16be5405d63d2bedbdfea 'WARNING: some request_irq() failures ignored in el2_open()', which exposed bug 1. This patch: 1. Replaces the use of probe_irq_{on,off}() with a real interrupt handler 2. Adds a delay before checking the interrupt-seen flag 3. Disables interrupts on all failure paths 4. Distinguishes error codes from the second request_irq() call, consistently with the first Compile-tested only. Signed-off-by: Ben Hutchings Signed-off-by: David S.

This requires order-4 allocation for txq->cmd[]. In situations like s2ram, this usually leads to allocation failure in the memory subsystem. The patch fixed this problem by allocating the Tx queues memory only at the first time. Later iwl_down/iwl_up only initialize but don't free and reallocate them. The memory is freed at the device removal time. BTW, we have already done this for the Rx queue.

This has always worked fine on my fast machine, but now I know there is a hidden race... The most likely candidate here is ring_control->device_idx. Quintin Pitts had already analyzed the culprit and posted a patch back in Oct 2009. But sadly, no one's picked up on this. ( https://patchwork.kernel.org/patch/53079/ [2 & 3] ). This patch does the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait.

Add RT3090 specific register initializations to rt2x00, based on the latest Ralink rt3090 vendor driver. Untested as I don't actually own an RT3090 based device, but given experiences on rt3070/rt3071 very hopeful that this will actually work..

Add RT3390 specific register initializations to rt2x00, based on the latest Ralink rt3390 vendor driver. Untested as I don't actually own an RT3390 based device, but given experiences on rt3070/rt3071 very hopeful that this will actually work..

The RX timestamps are extracted from the padding alingment bytes during the clean_rx_ring operation and copied into the skb_shared_hwtstamps struct of the skb. This extraction only happens if the rx_filter was set to something else than HWTSTAMP_FILTER_NONE with the SIOCSHWTSTAMP ioctl command. Hardware timestamping is only supported for eTSEC devices. To indicate device support the new FSL_GIANFAR_DEV_HAS_TIMER flag was introduced. Signed-off-by: Manfred Rudigier Signed-off-by: David S.

(Think raw interfaces.) If the device has ASF support enabled, the firmware requires the driver to enable VLAN tag stripping. If VLAN tagging is not explicitly supported by the kernel and ASF is enabled, the driver will have to reinject the VLAN tag back into the packet stream.

-- cgit v1.2.3 From 56b106ae7b1f6b7cef4ef7e79a03b59cfc940923 Mon Sep 17 00:00:00 2001 From: Giuseppe CAVALLARO Date: Tue, 13 Apr 2010 20:21:12 +0000 Subject: stmmac: rework normal and enhanced descriptors Currently the driver assumes that the mac10/100 can only use the normal descriptor structure and the gmac can only use the enhanced structures. This patch removes the descriptor's code from the dma files and adds two new files just for handling the normal and enhanced descriptors. Signed-off-by: Giuseppe Cavallaro Signed-off-by: David S.

But on 82599 the logic to disable/enable hardware stripping is different, and the code was not updated correctly when the hardware vlan stripping was enabled as default. This change comprises the creation of two new helper functions and calling them from the right locations to disable and enable hardware stripping of vlan tags at appropriate times.

Since the memory was already DMA mapped _before_ the call to write_tx_desc the device didn't get the txwi data at all or only sporadically. The call order is basically as follows (from rt2x00queue.c): 1) write_tx_data 2) rt2x00queue_map_txskb 3) write_tx_desc Hence, we shouldn't touch the skb in write_tx_desc anymore. To fix this issue create a new rt2800pci_write_tx_data callback and use it for updating the txwi _before_ the memory gets DMA mapped. The tx descriptor is still written (as before) in write_tx_desc. This patch allows basic TX on an rt305x soc device but I'm pretty sure that it will fix pci based cards as well. I can associate just fine with an AP now but I wasn't able to get a wpa secured connection working yet. Signed-off-by: Helmut Schaa Acked-by: Gertjan van Wingerde Signed-off-by: John W.

For this reason there is a need to pass some board specific data, like 'EEPROM is attached' flag or power control callback. However currently there is no way to pass this data through SDIO subsystem, so this patch registers dummy platform_device to allow that, until we have a better solution to this.

Rodriguez" Date: Thu, 15 Apr 2010 17:38:13 -0400 Subject: ath9k_hw: remove wrapper ath9k_hw_write_regs() This is used only once by ath9k_hw_process_ini() to write an array of phy registers through REG_WRITE_ARRAY(), but we already call REG_WRITE_ARRAY() multiple times on the same caller so just remove this pointless wrapper. We'll eventually just move the ath9k_hw_process_ini() caller as an callback to abstract away between different hardware families. Although this change is subtle I should note that this does change the delay pattern on writing the next series of registers. REG_WRITE_ARRAY() uses a counter for each register write and does a udelay(1) every 64 writes. By removing this call it means that the counter is processed for all the iniBB_RfGain registers and is incremented on ath9k_hw_process_ini(), before this the after the call ath9k_hw_write_regs() was made the register counter was kept at the same index number prior to the call.

Rodriguez" Date: Thu, 15 Apr 2010 17:39:13 -0400 Subject: ath9k_hw: restore mac address reading logic Once upon a time the AR_EEPROM_MAC macro was added to let us add a random attribute to the three 4-bytes of MAC addresses entries we read from the EEPROM. This was good while a random high-enough value was used which did not conflict with any of the already existing enum eeprom_param values. With AR9003 support the enums overlap and it means we either increment the random offset or just restore the reading logic to match what the HAL has. I choose to do the later to synchronize the logic on both code bases. This should fix reading the MAC address from the EEPROM on AR9003 hardware. Signed-off-by: Luis R.

It has been tested in an IBSS network where artifical IBSS merges have been done in order to trigger hundreds of rollover for the TSF lower part. It follows the logic mentionned by Derek, with only 2 register reads needed at each additional steps instead of 3 (the minimum number of register reads is still 3).

However TI recommends using deditated IRQ line for SDIO too. Add support for using dedicated interrupt line with SDIO, but also leave ability to switch to SDIO interrupts in case it's needed.

HW is configured to stop all DMA transactions to the host and sending packets to the network once parity error is detected, which is meant to prevent silent data corruption. At the same time HW generates the attention interrupt to every function of the device where parity has been detected so that driver can start the recovery flow.

The detailed phenomenon is 1. After a while the clients connected to one of these VAPs will get into a state that no broadcast/multicast packets can be transfered successfully while the unicast packets can be transfered normally. 2. Minutes latter the unitcast packets transfer will fail as well, because the ARP entry is expired and it can't be freshed due to the broadcast trouble. It's caused by the group key overwritten and someone discussed this issue in ath9k-devel maillist before, but haven't work out a fix yet. I referred the method in madwifi, and made a patch for ath9k. The method is to set the high bit of the sender(AP)'s address, and associated that mac and the group key. It requires the hardware supports multicast frame key search. It seems true for AR9160. Not sure whether it's the correct way to fix this issue. But it seems to work in my test. The patch is attached, feel free to revise it. Signed-off-by: Daniel Yingqiang ma Signed-off-by: John W.

Quoting from the changelog: This patch does it the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait. This is causing an issue with us referencing already freed memory, because some skb's we transmit, we immediately receive back, such as those for reading the eeprom (*) and getting stats. What can happen because of the moving of the tx processing to after the rx processing is that when the tasklet first runs after doing a special skb tx (such as eeprom) we've already received the answer to it. Then the rx processing ends up calling p54_find_and_unlink_skb to find the matching tx skb for the just received special rx skb and frees the tx skb. Then after the processing of the rx skb answer, and thus freeing the tx skb, we go process the completed tx ring entires, and then dereference the free-ed skb, to see if it should free free-ed by p54p_check_tx_ring()."

For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

This disables writeback batching and anything else that relies upon a delayed interrupt.

Testing note, running ifconfig up/down will not reproduce this issue because dev_open/dev_close call dev_deactivate() and then dev_activate().

It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.

The bonding driver calls ndo_vlan_rx_register() while holding bond->lock. The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while changing the vlgrp. The call also stops the cnic driver which sleeps while the bond->lock is held and cause the warning. This code path only needs to stop the NAPI rx handling while we are changing the vlgrp. Since no reset is going to occur, there is no need to stop cnic in this case. By adding a parameter to bnx2_netif_stop() to skip stopping cnic, we can avoid the warning.

To do this the pci_dev pointer that was in the rings has been replaced with a device pointer, and as a result all references to [tr]x_ring->pdev have been replaced with [tr]x_ring->dev.

Substitute DPRINTK macro for e_ that uses netdev_ and dev_ similar to e1000e. - Convert printk to pr_ where applicable. - Use common #define pr_fmt for the driver. - Use dev_ for displaying text in parts of the driver where the interface name is not assigned (like e1000_param.c). - Better align test with the new macros.

Summary of the changes: 1. Improved error handling. 2. Added the missing timeout arguments to usb_control_msg(). The following is a new Linux driver which exposes certain models of Sierra Wireless modems to the operating system as Network Interface Cards (NICs). This driver requires a version of the sierra.c driver which supports blacklisting to work properly. The blacklist in sierra.c rejects the interfaces claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic. The version of sierra.c which supports blacklisting is available from the sierra wireless knowledge base page for older kernels. It is also available in Linux kernel starting from version 2.6.31. This driver works with all Sierra Wireless devices configured with PID=68A3 like USB305, USB306 provided the corresponding firmware version is I2.0 (for USB305) or M3.0 (for USB306) and later. This driver will not work with earlier firmware versions than the ones shown above. In this case the driver will issue an error message indicating incompatibility and will not serve the device's USB-to-WWAN interface. Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c. A series of hook functions are provided in sierra_net.c which are called by usbnet.c in response to a particular condition such as receipt or transmission of a data packet. As such, usbnet.c does most of the work of making a modem appear to the system as a network device and for properly exchanging traffic between the USB subsystem and the Network card interface. Sierra_net.c is concerned with managing the data exchanged between the USB-to-WWAN interface and the upper layers of the operating system.

There is no synchronisation between the ISR read completion, and the interrupt deassert message. 2. A downstream read at the "wrong" moment can return 0, and suppress generating the next interrupt. Falcon should suffer from both of these, and it appears it does. Enable EFX_WORKAROUND_15783 on Falcon as well. Also, when we see queues == 0, ensure we always schedule or rearm every event queue.

In the second category, the command completion takes well more than 0.5ms (from 1.5ms upwards.)

After associated scans, the mac80211 does re-set the current channel, causing the join to occur. This would stop the hardware keep alive. To make the joins safer in this respect, this patch adds a join function that does the hardware-keep-alive magic along the join.

This is how they are implemented and what it says in the DebugFS documentation. DebugFS can not be compiled as a module. As a result, we only need to check for error pointers and particularly -ENODEV one time to know that DebugFS is enabled. This patch keeps the first check for error pointers and removes the rest. The other reason for this patch, is that it silences some Smatch warnings. Smatch sees the condition "(result != -ENODEV)" and assumes that it's possible for "result" to equal -ENODEV. If it were possible it would lead to an error pointer dereference. But since it's not, we can just remove the check. Signed-off-by: Dan Carpenter Signed-off-by: John W.

The comments in mac80211.h show there are actually three different, relevant variables, of which we are currently using two, both incorrectly. Fix this by making - ampdu_ack_len -> the number of ACKed frames (i.e. successes) - ampdu_ack_map -> the bitmap - ampdu_len -> the total number of frames sent (i.e., attempts) to match the header file (and verified with ath9k's usage) and updating Intel's RS code to match.

The MBM devices are instead identified by GUID. In order for cdc_ether to handle these devices the GUID in the MDLM descriptor is tested. All MBM devices currently handled by cdc_ether as well as future CDC Ethernet MBM devices can be identified by the GUID.

RCU conversion is pretty much needed : 1) Add a new structure, called "struct socket_wq" to hold all fields that will need rcu_read_lock() protection (currently: a wait_queue_head_t and a struct fasync_struct pointer). [Future patch will add a list anchor for wakeup coalescing] 2) Attach one of such structure to each "struct socket" created in sock_alloc_inode(). 3) Respect RCU grace period when freeing a "struct socket_wq" 4) Change sk_sleep pointer in "struct sock" by sk_wq, pointer to "struct socket_wq" 5) Change sk_sleep() function to use new sk->sk_wq instead of sk->sk_sleep 6) Change sk_has_sleeper() to wq_has_sleeper() that must be used inside a rcu_read_lock() section. 7) Change all sk_has_sleeper() callers to : - Use rcu_read_lock() instead of read_lock(&sk->sk_callback_lock) - Use wq_has_sleeper() to eventually wakeup tasks. - Use rcu_read_unlock() instead of read_unlock(&sk->sk_callback_lock) 8) sock_wake_async() is modified to use rcu protection as well. 9) Exceptions : macvtap, drivers/net/tun.c, af_unix use integrated "struct socket_wq" instead of dynamically allocated ones. They dont need rcu freeing. Some cleanups or followups are probably needed, (possible sk_callback_lock conversion to a spinlock for example...). Signed-off-by: Eric Dumazet Signed-off-by: David S.

Tsirkin" Date: Wed, 17 Mar 2010 17:45:01 +0200 Subject: tun: add ioctl to modify vnet header size virtio added mergeable buffers mode where 2 bytes of extra info is put after vnet header but before actual data (tun does not need this data). In hindsight, it would have been better to add the new info *before* the packet: as it is, users need a lot of tricky code to skip the extra 2 bytes in the middle of the iovec, and in fact applications seem to get it wrong, and only work with specific iovec layout. The fact we might need to split iovec also means we might in theory overflow iovec max size. This patch adds a simpler way for applications to handle this, and future proofs the interface against further extensions, by making the size of the virtio net header configurable from userspace. As a result, tun driver will simply skip the extra 2 bytes on both input and output. Signed-off-by: Michael S. Tsirkin Acked-by: David S.

The original orinoco_usb patches had a boolean variable controlling whether spin_lock_bh was used, or irq based locking. This version provides wrappers for the lock functions and the drivers specify the functions pointers needed. This will introduce a performance penalty, but I'm not expecting it to be noticable.

The low level hermes routines (for local bus cards) are replaced, the driver supplies its own ndo_xmit_start function, and locking is done with the _bh variant. Some recent functionality is not available to the USB cards yet (firmware loading and WPA). Out-of-tree driver originally written by Manuel Estrada Sainz.

Also, to debug mac80211 code itself, make hwsim "support" aggregation sessions. It will still just transfer the frame, but go through the setup and teardown handshakes.

Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which came with a driver CD containing a Linux driver. This driver turns out to be a copy of dm9601.c with symbols renamed and my copyright stripped. That aside, it did contain 1 functional change in dm_write_shared_word(), and after checking the datasheet the original value was indeed wrong (read versus write bits). On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s. On other devices the difference is less spectacular, but still significant (~30%).

I already tested it for bridge, bonding, bridge over bonding, and bonding over bridge. It looks fine now. To make bridge and bonding support netpoll, we need to adjust some netpoll generic code. This patch does the following things: 1) introduce two new priv_flags for struct net_device: IFF_IN_NETPOLL which identifies we are processing a netpoll; IFF_DISABLE_NETPOLL is used to disable netpoll support for a device at run-time; 2) introduce one new method for netdev_ops: ->ndo_netpoll_cleanup() is used to clean up netpoll when a device is removed. 3) introduce netpoll_poll_dev() which takes a struct net_device * parameter; export netpoll_send_skb() and netpoll_poll_dev() which will be used later; 4) hide a pointer to struct netpoll in struct netpoll_info, ditto. 5) introduce ->real_dev for struct netpoll. 6) introduce a new status NETDEV_BONDING_DESLAE, which is used to disable netconsole before releasing a slave, to avoid deadlocks.

The code in question is: * too big and complex (more than 550 SLOC.) This is enough to qualify for a new separate code file! * unbalanced quantity & quality over-engineered areas like: * xmit scheduling and queuing frames for multiple HT peers * redundant frame sorting are confronted by gaping holes: * accurate transmission feedback * firmware error-handling and device reset * HT rate control algorithm * error-prone Since its inclusion, hardly anything was done to fix any of the outlined flaws from the initial commit message. => This also indicates poor maintainability. * relies heavily on several spinlocks. As a result of this shortcomings, the code is slow and does not even support the most basic 11n requirement: HT station mode. Therefore, I request to purge my heap of **** from the kernel: "ar9170: implement transmit aggregation". The next item on the agenda is: (re-)start from scratch with an adequate design to accommodate the special requirements and features of the available frameworks and tools.

In order to improve this situation, first make the configuration APIs (cfg80211 and nl80211) aware of multi-channel operation -- we'll eventually need that in the future anyway. There's one userland API change and one API addition. The API change is that now SET_WIPHY must be called with virtual interface index rather than only wiphy index in order to take effect for that interface -- luckily all current users (hostapd) do that. For monitor interfaces, the old setting is preserved, but monitors are always slaved to other devices anyway so no guarantees. The second userland API change is the introduction of a per virtual interface SET_CHANNEL command, that hostapd should use going forward to make it easier to understand what's going on (it can automatically detect a kernel with this command). Other than mac80211, no existing cfg80211 drivers are affected by this change because they only allow a single virtual interface. mac80211, however, now needs to be aware that the channel settings are per interface now, and needs to disallow (for now) real multi-channel operation, which is another important part of this patch. One of the immediate benefits is that you can now start hostapd to operate on a hardware that already has a connection on another virtual interface, as long as you specify the same channel. Note that two things are left unhandled (this is an improvement -- not a complete fix): * different HT/no-HT modes currently you could start an HT AP and then connect to a non-HT network on the same channel which would configure the hardware for no HT; that can be fixed fairly easily * CSA An AP we're connected to on a virtual interface might indicate switching channels, and in that case we would follow it, regardless of how many other interfaces are operating; this requires more effort to fix but is pretty rare after all Signed-off-by: Johannes Berg Signed-off-by: John W.

This is clearly undesirable, since the new one might switch to no-HT while another one is operating in HT. Address this issue by keeping track of the HT mode per interface, and allowing only changes that are compatible, i.e. switching into HT40+ is not possible when another interface is in HT40-, in that case the second one needs to fall back to HT20. Also, to allow drivers to know what's going on, store the per-interface HT mode (channel type) in the virtual interface's bss_conf. Signed-off-by: Johannes Berg Signed-off-by: John W.

But transmission of beacons goes through the normal SKB queue maintained in hif_usb, leading to a situation where __skb_dequeue() in the TX completion handler goes kaput. Fix this by simply getting a beacon from mac80211 for every SWBA and free it in its completion routine. Signed-off-by: Sujith Signed-off-by: John W.

The reason for this is that the firmware JOIN command clears WPA(2) key material, and if done while associated to a WPA(2) secured AP, will render the data-path unusable. While the channel is not usually changed while associated (and currently we could not even support something like that), after performing a scan operation while associated, mac80211 will re-set the current channel to the driver. This caused our problem. Also, the mac80211 is assuming that the driver channel configuration remains persistent over periods of IDLE.

However, only a few drivers made use of it, and the userspace helpers are deprecated anyways. Therefore, get rid of dev_node_t . As a first step, remove any usage of dev_node_t from drivers which only wrote to this typedef/struct, but did not make use of it.

However, the function calling unregister_netdev() was only ever called by the PCMCIA core if register_netdev() succeeded previously. The lonely exception was easily fixed.

All of the driver's kick_tx_queue callback functions treat the TX queue for beacons in a special manner. Clean this up by integrating the kicking of the beacon queue into the write_beacon callback function, and let the generic code no longer call the kick_tx_queue callback function when updating the beacon.

I did this because request more accurately represents what it actually does. Also, I added a string based ABI for users wanting to use a string interface. So if the user writes 0xDDDDDDDD formatted hex it will be accepted by the interface. (someone asked me for it and I don't think it hurts anything.)

It is thus not available for later cases when we need to restore stations and need to send the link quality command afterwards. Now, when first adding the broadcast station, also generate its link quality command to always be available for later restoring. Also fix an issue when adding local stations where the "in progress" state is never cleared.

That leads to a bug with injection -- it is currently not possible to inject frames when the only virtual interface is a monitor, because in that the required broadcast station is missing. Additionally, allocating and deallocating the broadcast station's LQ all the time is wasteful, and the code to support this is fairly complex. So this changes completely the way we manage the broadcast station. Rather than manage it along with any interface, we now allocate it when we bring the device up, and remove it again when we bring the device down. When we bring the device up, we don't immediately program the broadcast station into it, instead we just mark it active and rely on the next restore cycle to upload it to the device. This works because an unassociated RXON is always required at least once to set up device parameters, which implies a reprogramming of stations into the device. As we now manage all stations properly, there no longer is a need for forcing a clearing of them via iwl_clear_ucode_stations(), which can become a lot simpler.

A consequence of that is that the driver will know that it is not communicating on HT anymore, but the rate scaling table is still under the impression it is operating in HT. Any time after driver has been notified channel is not HT anymore there will thus be a firmware SYSASSERT when the current active LQ command is sent. A workaround for this issue is to not send a LQ command in the short time between being notified channel is not HT anymore and rate scaling table being updated.

Remove iwl_get_sta_id() and use iwl_sta_id() instead as appropriate. This reduces the amount of code needed to find the right station significantly, and works since mac80211 passes the station only after it has been fully initialised, ie. even if TX races with station addition it will only be passed to TX once the addition is complete.

Also, instead of dropping them immediately though move the check *after* we check for all sort of frame errors. This should enable us to discard these frames if the hardware picks other bogus items first. Lets see if we still get those jumbo counters increasing still with this. Jumbo frames would happen if we tell hardware we can support a small 802.11 chunks of DMA'd frame, hardware would split RX'd frames into parts and we'd have to reconstruct them in software. This is done with USB due to the bulk size but with ath5k we already provide a good limit to hardware and this should not be happening. This is reported quite often and if it fills the logs then this needs to be addressed and to avoid spurious reports. Cc: stable@kernel.org Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

RANGE_OSDAC is set to 0x1 for 2G, 0x0 for 5G 2. offsetC1 is set to 0xc 3. inv_clk320_adc is set to 0x1 * To reduce PHY error(from spur), cycpwr_thr1 and cycpwr_thr1_ext are increased to 0x8 at 2G. * The 2G Rx gain tables are updated with mixer gain setting 3,1,0.

Therefore, on SDIO interface, the reset event should be still detected and handled by dev_reset_handle(). Problem description: Whenever a reboot barker is received during operational mode (i2400m->boot_mode == 0), dev_reset_handle() is invoked to handle that function reset event. dev_reset_handle() then sets the flag i2400m->boot_mode to 1 indicating the device is back to bootmode before proceeding to dev_stop() and dev_start(). If dev_start() returns failure, a bus reset is triggered by dev_reset_handle(). The flag i2400m->boot_mode then remains 1 when the second reboot barker arrives. However the interrupt service routine i2400ms_rx() instead of invoking dev_reset_handle() to handle that reset event, it filters out that boot event to bootmode because it sees the flag i2400m->boot_mode equal to 1. The fix: Maintain the flag i2400m->boot_mode within dev_reset_handle() and set the flag i2400m->boot_mode to 1 when entering dev_reset_handle(). It remains 1 until the dev_reset_handle() issues a bus reset. ie: the bus reset is taking place just like it happens for the first time during operational mode. To denote the actual device state and the state we expect, a flag i2400m->alive is introduced in addition to the existing flag i2400m->updown. It's maintained with the same way for i2400m->updown but instead of reflecting the actual state like i2400m->updown does, i2400m->alive maintains the state we expect. i2400m->alive is set 1 just like whenever i2400m->updown is set 1. Yet i2400m->alive remains 1 since we expect the device to be up all the time until the driver is removed. See the doc for @alive in i2400m.h. An enumeration I2400M_BUS_RESET_RETRIES is added to define the maximum number of bus resets that a device reboot can retry. A counter i2400m->bus_reset_retries is added to track how many bus resets have been retried in one device reboot. If I2400M_BUS_RESET_RETRIES bus resets were retried in this boot, we give up any further retrying so the device would enter low power state. The counter i2400m->bus_reset_retries is incremented whenever dev_reset_handle() is issuing a bus reset and is cleared to 0 when dev_start() is successfully done, ie: a successful reboot.

The intention is to bring back the device to some known state whenever TX sees -110 (-ETIMEOUT) on copying the data to the HW FIFO. The TX failure could mean a device bus stuck or function stuck, so the current error recovery implementation is to trigger a bus reset and expect this can bring back the device. Since the TX work is done in a thread context, there may be a queue of TX works already that all hit the -ETIMEOUT error condition because the device has somewhat stuck already. We don't want any consecutive bus resets simply because multiple TX works in the queue all hit the same device erratum, the flag "error_recovery" is introduced to denote if we are ready for taking any error recovery.

When a device reset happens and the TX FIFO is released/re-allocated, a new block of memory may be allocated for the TX FIFO, therefore tx_msg should be cleared so that no any TX threads (tx_worker, tx) would access to the out-of-date addresses. Also, the TX threads use tx_in and tx_out to decide where to put the new host-to-device messages and from where to copy them to the device HW FIFO, these indices have to be cleared so after the TX FIFO is re-allocated during the reset, the indices both refer to the head of the FIFO, ie. a new start. The same rational applies to tx_msg_size and tx_sequence. To protect the indices from being accessed by multiple threads simultaneously, the lock tx_lock has to be obtained before the initializations and released afterwards.

The handling of tx descriptors for beacons can be simplified by updating write_tx_desc implementations of each driver to write directly to the queue entry descriptor instead of to a provided memory area. This is also a preparation for further clean ups where descriptors are properly reserved in the skb instead of fiddling with the skb data pointer.

The 82577-specific force_speed_duplex function also had an issue where it disabled Auto-MDI-X which caused the link to not come up.

The ARC subsystem is currently only available on 80003es2lan and 82573 parts supported by the driver. A new flag, has_fwsm, is introduced to be used when checking if manageability is enabled but only on parts that acutally have an FWSM register. While the above parts have an FWSM register, there are other parts that have FWSM but do not have support for the ARC subsystem, namely 82571/2 and ICHx/PCH. And then there are parts that have manageability, but do not have either FWSM register or support for the ARC subsystem - these are 82574 and 82583. For 80003es2lan, 82571/2/3 and ICH/PCH parts, this patch makes no functional changes, it only corrects the usage of the manageability flags. For 82574 and 82583, it fixes the incorrect accesses of the non-existent FWSM register and ARC subsystem as well as corrects the check for management pass-through.

However, e1000_lan_init_done_ich8lan() had already been called in one of the two places where PHY reset occurs for ICHx/PCHx parts, which caused the second call to busy-wait for 150 msec because the LAN_INIT_DONE bit had already been checked and cleared. ii) Cleanup the two separate PHY reset code paths, i.e. the full-chip reset in e1000_reset_hw_ich8lan() and the PHY-only reset in e1000_phy_hw_reset_ich8lan(). There was duplicate code in both paths to be performed post-reset that are now combined into one new function - e1000_post_phy_reset_ich8lan(). This cleanup also included moving the clearing of the PHY Reset Asserted bit in the STATUS register (now done for all ICH/PCH parts) and the check for the indication from h/w that basic configuration has completed back to where it previously was in e1000_get_cfg_done_ich8lan(). iii) Corrected a few comments Signed-off-by: Bruce Allan Signed-off-by: Jeff Kirsher Signed-off-by: David S.

a0ba676008d9f050f1de9ede8d1ee4bf6820bfc9 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Mon, 17 May 2010 17:34:43 -0700 Subject: bnx2: Use netif_carrier_off() to prevent timeout. Based on original patch from Stanislaw Gruszka . Using netif_carrier_off() is better than updating all the ->trans_start on all the tx queues. netif_carrier_off() needs to be called after bnx2_disable_int_sync() to guarantee no race conditions with the serdes timers that can modify the carrier state. If the chip or phy is reset, carrier will turn back on when we get the link interrupt. If there is no reset, we need to turn carrier back on in bnx2_netif_start(). Again, the phy_lock prevents race conditions with the serdes timers. Signed-off-by: Michael Chan Signed-off-by: Matt Carlson Signed-off-by: David S.

Enic dynamic devices are just like normal enic eth devices except dynamic enics require an extra configuration step to assign a port-profile identifier to the interface before the interface is useable. Once a port-profile is assigned, link comes up on the interface and is ready for I/O. The port-profile is used to configure the network port assigned to the interface. The network port configuration includes VLAN membership, QoS policies, and port security settings typical of a data center network. A dynamic enic initially has a zero-mac address. Before a port-profile is assigned, a valid non-zero unicast mac address should be assign to the dynamic enic interface.

The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states: "Between two commands at least one internal clock cycle is needed in order to proceed. The internal clock is half of the external oscillator frequency." On SMP systems the current implementation leads to a write stall in the tx-path, which can be solved by adding some general locking and some time to settle the write_reg() operation for the command register. Thanks to Klaus Hitschler for the original fix and detailed problem description. This patch applies on net-2.6 and (with some offsets) on net-next-2.6 .
